The South African Railways Class 8R 4-8-0 of 1930 was a steam locomotive.
In 1901 and 1902, the Cape Government Railways placed sixteen 8th Class 2-8-0 Consolidation type steam locomotives in service. In 1912, when they were assimilated into the South African Railways, they were renumbered and reclassified to Class 8X. One of them was reboilered and converted to a 4-8-0 Mastodon type wheel arrangement in 1930 and reclassified to Class 8R.[1][2][3]
The first 8th Class 2-8-0 Consolidation type locomotive of the Cape Government Railways (CGR) was designed by H.M. Beatty, the Chief Locomotive Superintendent of the CGR from 1896 to 1910. Fourteen of these engines were built by the American Locomotive Company (ALCO) in 1902.[1][4][5]
They were conceived as mixed traffic locomotives, equally suitable for goods and passenger work, and had bar frames, narrow fireboxes, used saturated steam and had cylinders with overhead slide valves which were actuated by inside Stephenson valve gear. The Type WG bogie tender entered service with these engines.[1][3]
South African Railways
When the Union of South Africa was established on 31 May 1910, the three Colonial government railways (CGR, Natal Government Railways and Central South African Railways) were united under a single administration to control and administer the railways, ports and harbours of the Union. Although the South African Railways and Harbours came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways were only implemented with effect from 1 January 1912. In 1912, these Consolidation types were designated Class 8X on the South African Railways (SAR).[2][6]
